Pseudo code explains the Pollard’s Rho procedure  This method picks two modulo N congruent numbers x and y.  Modulo N numbers: We are considering a finite set of numbers that is [0, n).  if y = x mod n, that means that (y-x) is a multiple of n  If GCD [ (x-y), N ] is not equal to 1 or N, then we just proved the compositeness of the number N. else we will pick another random x number to repeat the procedure.  Next random number is chosen by a polynomial While TRUE do print d
